Started with a single-store, single-department pilot in dairy. Measured 17 hours/week labor saved on tag updates. Expanded to full store in 8 weeks, then to 5 stores per quarter for the next 4 quarters.

Key win: eliminated price-mismatch consumer-protection risk in a strict-enforcement state. Saved $22K/store/year in fines and customer-service time alone.

"We piloted three vendors in parallel. ZKong via Retail Digitals was the fastest to ship and the only one with a US team that answered the phone the same day."

Hardware mix: Valley series for shelves, Shield freezer for cold aisles, Arrow strips in produce.

Pharmacy chain

Independent pharmacy chain — 9 locations, Midwest

ESLs deployed

Driven by FDA labeling compliance. Manual paper tags couldn't keep up with weekly OTC pricing changes plus required allergen and dosage text updates.

Deployed Quantum ultra-narrow-bezel labels (BWRY) for all OTC and beauty aisles. Cloud Platform integrated with their existing Inventory + Pharmacy Management System via REST API.

"Our compliance audit team went from a 12-hour weekly task to a 30-minute spot-check. The platform shows when every label was last updated and what changed."

Hardware mix: Quantum 2.3"-3.5" across all OTC; Blade 4.2" for shelf-talkers; Shield for refrigerated medications.

Cannabis retail

Multi-state cannabis dispensary — 6 stores, West Coast

Per-batch THC%/CBD% updates were impossible to keep current with paper. Each new batch arrival triggered a 4-hour manual relabeling cycle. Cloud Platform integration with their Metrc seed-to-sale system automated this entirely.

State-specific compliance text (warnings, age restrictions) auto-applied per store location, eliminating manual overrides during multi-state expansion.

"The compliance audit risk alone was worth more than the labor savings. We can prove every label was current within 5 seconds of any batch arrival."

Hardware mix: Quantum series for premium aesthetic, Essence 7.3" for endcap brand displays.
